Stambaugh's

What Stambaugh's does

Stambaugh's, Inc. is a privately held, family-owned (now second-generation) and veteran-owned construction company headquartered in Union Bridge, Maryland, founded in 1973 by Charles R. Stambaugh. The company provides a vertically integrated suite of heavy-civil and site-development services — excavation and grading, underground utilities (sewer, storm, water main), concrete construction, redi-mix concrete supply, paving, portable crushing and screening, recycled materials sales, equipment repair, and sediment control/environmental services — across Carroll and Frederick counties and the broader Maryland region. Core operating technology consists of an owned heavy-equipment fleet including portable jaw crushers and screeners (24"x36" capacity), front discharge mixer trucks, and a specially fabricated six-wheel-drive mulcher and blower truck for steep-terrain sediment control; the company also operates an in-house redi-mix concrete plant and a materials recycling line producing RC #6 and RC #2 aggregates.

The business model is project- and transaction-based: customers pay for construction services on a quote basis across subdivisions, commercial site jobs, county roadways, parks, agricultural installations, and quarries, while redi-mix concrete and recycled aggregates are sold per-yard/ton to homeowners, contractors, and developers. Go-to-market is sales-led and relationship-driven, relying on direct field engagement with developers, general contractors, homeowners, farmers, inspection authorities, and environmental agencies rather than digital marketing. Revenue mechanics combine professional-services contracts (utilities, excavation, concrete installation) with product/transaction revenue (concrete, aggregates). The company serves a diversified customer base spanning healthcare (Carroll Hospital Center), retail (Food Lion, Pizza Hut), banking (New Windsor State Bank), government/fire-company (New Windsor Fire Company), national homebuilders (K Hovnanian, Dan Ryan Builders), local masonry and concrete subcontractors, and agricultural operations (Coldsprings Farm, Rocky Point Farm). No revenue is publicly disclosed, no external funding rounds are present, and there are no subsidiaries, M&A activity, or geographic expansion beyond Maryland in the source material.
